Amazon EC2 (Elastic Cloud Computing) is used for IAAS (Infrastructure As A Service) Cloud. It is used using creating Linux & Windows instances in the cloud. After creating instances, we need to access them remotely. During creation of instances, we need to specify the keypair that we are going to use for accessing instances. Step by step procedure for creating keypair in Amazon AWS Cloud.

Step 1: login at “aws.amazon.com” using your account

Step 2: Choose “EC2” from compute services

Step 3: All the resources which has been created or deployed will be shown. As can be seen, no keypair has been created. Click on “Key Pairs” for creating new keypair.

Step 4: Press “Create Key Pair” button.

Step 5: Give some name to keypair. In our case, we have given the name “vipin”.

Step 6: It will ask to save your key. It is saving the key as “vipin.pem”. We saved the key on the desktop.

Step 7: This dashboard screenshot shows the key and its fingerprint.

Step 8: We also created 1 folder “keys” in our “F:” drive and also download 2 utilities called “putty” and “puttygen”. “putty” is used for remotely accessing linux instance. But the problem with this utility is that it can not use the key in “pem” format. We need to convert the key from “pem” format to “ppk” format using “puttygen”.

Step 9: Open “puttygen” utility. It will show some warning message. Just click on “Run“.

Step 10: It has started the Putty Key generator utility.

Step 11: Click on “File” menu & choose “Load private key”.

Step 12: Select “vipin.pem” & click on “Open” for loading the key.

Step 13: It will show the message that key has been imported successfully.
